That's interesting, but counter-intuitive to me: what's the
advantage
of having the irrigation underneath?

Saves water.
Less evaporation.

A good reason. So you don't get a problem with the holes blocking up,
or over-enthusiastic roots getting in?

Not so far. It's the first year I've used it, I can just pour a couple of
cans of water in, and it goes right to the roots. I'll post later in the
year if there are any problems with it, if you're interested.

After everything is over for this year, I plan to put a T in the pipe, lead
it outside and connect to the guttering so it gets watered inside the
greenhouse when it rains. Sometimes work prevents me getting to the
allotment as often as I like, so this will hopefully prevent some losses.
